Yeh more practise is the answer I guess, I think the problem is I have not done enough extreme bends at that part of the neck before now. reb both of my strats have 9.5 radius fretboards & Robert my USA Standard does fret out it needs a fret dress & setup.
DB I use 10-46 strings on my guitars, I did not like 9-42's.
Thanks for your input practise, practise & I will get there.
On another note I have been told that SRV had to superglue his fingernails to the quicks on his fingers from doing bends on the heavy strings he was using 13-58's, OUCH!!
EDIT. I have just modified the angle of the three springs in the back cavity on my Strat from this ||| to this /|\ and that has lowered the string tension enough to make string bends so much easier. I guess you learn something new every day
