Opinions on reground stock intake cam

Hi people,

Bought a couple months ago a Race kit intake cam for the Gen3, but when I got it and measured it turned out to be only a 9.1mm lift cam so I'm having it returned.
Now, I'm thinking of having a stock cam reground to 9.7mm retaining the same 300 deg duration for about 300 euros (Is this a reasonable price?)
Has anyone tried these sort of specs?

Also has anyone managed to get great results in midrange with the stock cam?
Is 105ļ really the best compromise for the stock cam?
This is a Track bike only.

Thanks

done couple of gen 1 engines with gen 3 race int, stk gen 1 ex. cam. potent combo, strong midrange, about 190 hp with ported/milled head, .45 mm hg, int 110-111/ex 108, good tune. added compression with these cam #'s. 5.6's/128-8.7's/158. that's good accleration. also have run 2 sets stk lift reground webs 356/335 lift with 252 degrees duration@.050. about $500 for the pair here. same engine mods, these small cams are sleepers, strong mid/top end but cam degree different. ran strongest at 107 in/104 ex. added compression/ tight squish helps any of these cams make broader power which ur asking for. best proven gen 1 stk cam #'s 107/104. stk gen 1 cams make strong low/mid power. as far as durations, cam companies quote durations usually at .040-.050 valve lift. that gen 3 race int. has 243 degrees duration @.050 lift to give u some perspective.
