It's been a long time since I tried the 2015 Blade 98 18x20, so I can only compare the DR 98 to the 2015 Blade 98 16x19 (which I just recently sold) and the 2013 Blade 98 18x20 (which I owned for a while a year+ ago).
My DR 98 is strung with msv hex which is a new string for me, but it falls in the std poly category imo. That being said, the DR 98 feels very muted in comparison to the blades. I thought the 2015 Blade 98 16x19 was an ok frame, but it def felt a bit hollow and tinny, esp compared to solid frames (IGPP, PS97S, XFP95 aso), and also when compared to the 2013 Blade 98 18x20.
Imo, the Textreme Tour 95 is a much better frame for that old/new hybrid thing, compared to the 2015 Blade 98 16x19.
I produce great baseline shots with the DR98 though, but it's def in the Pure Aero/Drive, Warrior, Tour 100 category.
Right now, I'd love a PST with the spin-game qualities of the DR98.
Or a TT95 with the punch of the PST.
