Full poly - unpredictable stringbed?

[pico]

I usually play with full poly and starting to notice more unpredictable output e.g. more forehands will tend to suddenly launch higher up (almost moonball level sometimes) than I would expect them too. I have experimented with low tension (40 - 45lbs) and high tension (mid 50s and above). I have used mostly shaped poly but also some that are mildly shaped e.g. RPM Team, Lynx Tour but the same observation holds. This is compared to a hybrid setup of multifilament mains and poly crosses which I am starting to enjoy more cos my shots seem to go where I want them to more often. Anyone else have this same observation? I should mention that this seems to be the case for whatever racquet I try - PAVS, Gravity Pro etc.

Strings are losing too much tension so strings are not snapping back in a reliable manner. This is a hallmark of time to change out your polyester strings. (There are other indicators...) You want to decrease the rate of tension loss, so if you're using 1.25mm, go thicker such as 1.30mm. Multis also lose tension, but not as quickly as polys.

This happens to me on a freshly strung racquet too though. I observed this yesterday with a Gravity Pro. I had RPM Team 1.25 on mains at 55lbs and Lynx Tour 1.20 on crosses at 53lbs.

If you are spraying balls with fresh strings, it is not a string job issue. I have clients using SPPP 1.23mm at 53-56# in FB Blade 98 16x19 and they're not spraying shots until like their 20th session. (~12-16 hours).

Quick question..who does your stringing? Has something changed at that end?

This is very true

Are you stringing two-piece string jobs? If so, is the tension between the two too far apart? I hate two piece string jobs. Try stringing a one piece at one tension. It's way more consistent.

I do my own stringing and nothing changed.

I use a hybrid setup.

Too much arming, swing too slow.

You can try lowering your crosses tension.

Second this. As consistent as most of us like to think we are, we all make way more mistakes than we want to admit. Always double-check your technique. Little issues can have big effects on how your shots look.

There is something to account for the first hit right off the machine as I do believe an hour of hitting helps the poly settle and then it should be pretty consistent from there until it dies.

I don't blame strings when I miss a shot

The only variable that hasn't changed is the player. I don't think it's the strings or frame

Higher launch angle and grip from full bed of shaped poly compared to multi/poly. Gives you a higher chance to launch the ball up on a bad hit.

This unpredictability with shaped poly strings has been reported many times. The pros only use round poly. I wonder why.

Given the same swing path, spin is achieved either through friction or snapback. With full bed poly this snapback action is accentuated, hence sometimes the ball either spins too much leaving it short or it launches long if you don't get around the ball and swing with enough velocity. That's why full poly is more challenging to play with vs. either solid core or multifibre syn gut.

A good solution is to do what you have done. Hybrid a syn gut with a poly (on the mains or crosses and vice versa).
