This is my experience from comparative playtesting of the HEAD 360+ Gravity MP (my son's) vs 360+ Radical MP (pro shop demo). 8 hours total - 5hrs rallies and drills; 3hrs of sets. Playstyle - attacking all-court (evolved from 1980s S&V as grasscourts disappeared); single-handed backhand; likes to finish points at net. Played with Prestige Tour 600 for 20+ years before switching to Gravity Tour last year. Current spec preference - 340g/BP32.7cm(5HL)/SW340.
Disclaimer: this is my own experience, YMMV! I will start of by saying that both are great racquets and I would happily play either in recreational and match play.
Specs (a very pleasant coincidence of being pretty close!):
Gravity MP - 324g / BP 33.3cm / SW 330 (includes +8g for OG and Dampener and +5g BluTack under buttcap. Came in a bit head heavy, hence the overspec SW). 100sq inch; 16x20 with 6 mains in throat. Relatively open pattern.
Radical MP - 326g / BP 33cm / SW 329 (includes +8g for OG and Dampener). 98sq inch; 16x19 with 8 mains in throat. The string spacing is noticeably closer in the Radical MP.

Feel: (This is a little long, but I can't help it when it comes to HEAD racquets!).
Gravity MP - plush and very comfortable on the arm; feels every bit its RA of 62. Generous sweet spot, slightly above centre location as per the egg-shaped hoop. The racquet flexes in uniform manner from throat to hoop typical of traditional constant beam designs (22mm on this stick). Good pocketing. If you like the feel of classic HEAD racquets, this is not quite there but as close as one can get in a 11.5oz tweener. Slight flutter in the upper hoop when impact is off-centre high; still good power. Notable dead areas in the lower hoop on either side of the mid-axis corresponding with where the egg-shaped hoop is narrower. Don't make contact here, the ball will head straight to the bottom of the net!
Radical MP - crisp/firm but comfortable, feels as expected for RA of 65. Smaller sweet spot but still a good size; more centred in keeping with the slightly rectangular shaped hoop. The racquet flexes mostly at the throat than the hoop which is exceptionally stable. Fabulous pocketing; almost feels like a catcher's mitt on ball impact! Consistent stringbed response with hardly any hoop flutter. I think HEAD has done a remarkable job with the hoop design of the Radical MP. It's a very well refined variable beam 20/23/21mm. Overall, this is nowhere near as plush as the Gravity MP, but many will likely favour the more raw, direct and connected feel of the Radical MP.
Cosmetics: I'm probably not the right person to ask, being in my 5th decade! The Gravity MP flip cosmetics looks odd to me, but at least it's mostly a non-distracting satin black. The Radical MP could be used as an airport runway signalling paddle. Paint quality is top notch and can take a beating - great job HEAD! Beam thickness is a relatively svelte 22mm on the Gravity MP and with it's relatively narrow near box-beam cross section, feels great in the left hand for someone who uses a SHBH. The Radical MP has a more prominent triangular beam cross section. It's a little clunky in the left hand; but I'm a narrow box-beam guy.
Maneueverability: Both racquets can be whipped around with speed and ease as expected for 11.5oz weight. Gravity MP is 100sq inches, but doesn't feel or look noticeably larger than the Radical MP.
Groundies:
Gravity MP - higher launch angle with very easy access to topspin. Plays better with a spin-focused (windshield wiper) stroke than a flatter technique. Hits a great banana FH on the run. Not as precise when going for the lines. Best for players who hit slightly above centre. If you tend to hit low in the hoop, the stringbed can be inconsistent in response. BH slices are average and tend to float; but it's my worst shot. Ironic given that my BH top/drive are my strongest shots! Generous power level (actually, too much for me. But I normally use heavier, more controlled racquets).
Radical MP - lower launch angle with excellent controlled trajectory. Good spin potential but played best for me with a flatter stroke technique. Precise when aiming for the lines for winners, the 8-throat mains advantage is clearly felt on these shots. Encourages an attacking game style. Deadly on slice BHs - I hit some of my best with this stick and I'm typically mediocre with slices. Consistent stringbed performance and will suit just about anyone. Bags of free power (in reality, excessive for me and I had to consciously reign in my strokes somewhat). However, the ball sails less often than with the Gravity MP. Score one for HEAD's "Control Pattern" stringbed.
Volleys: No contest, the Radical MP is superior due to the combination of the closer string spacing and highly stable hoop. Anything above net height is a direct, precise knife-down. Shoe-lace pick-ups are easier to keep low and controlled over the net.
Serves: Slices and flats are better with the Radical MP; kickers are better with the Gravity MP. Easier to crank the big ones with the Radical MP due to more free power. However, there's a lot going for the Gravity MP when it comes to the second serve kickers.
Returns: Radical MP is more stable against heavy serves. Gravity MP has a touch of hoop flutter against big serves, but the softer flex and more spinny stringbed makes it easier to hit angled, diving returns against a net-charging opponent.
Touch shots: Drops and short angle off-paced shots are easier with the Gravity MP. The soft feel is a big advantage with such shots.
Overall:
As said at the start of my review, both are great racquets and I would happily use either (with some weight additions to get them into my preferred heavier spec range). I would also have liked to try the Radical Pro as part of this comparative playtest, but UK Covid lockdown put an end to that hope.
I think the Radical MP will outsell the Gravity MP on account of it's greater free power, exceptionally stable hoop and more consistent stringbed. Particularly if one is coming from the direction of a Pure Aero/Drive, the Gravity MP is probably a bridge too far. However, if one is an old-school HEAD fan and likes plush sticks, the Gravity line has a lot going for it in terms of feel and traditional beam/hoop flex. Since that's where I come from, the Gravity MP is my pick. However, my sneaky suspicion is that I would probably win more matches over the long term with the Radical MP!
(If this was 1985 and I was back playing grasscourt S&V tennis, I'd take the Radical MP everytime on account of superior slice serves, slice BHs and volleys. However, this is 2021 and that type of tennis has largely disappeared.)
Given my longstanding respect and love for the HEAD brand heritage, it's great to see the course correction and much improved feel in their racquets with the 360+ lines. A BIG step in the right direction and hopefully a sign of more good stuff to come!
