my two cents,, how does it shoot,, if great,, then the tiller is ok,,
it does appear braced the bottom limb is a bit weaker,,
at full draw not so much,, so your call,, sometimes on longer bow,, that much difference is not effecting the way it shoots too much,, if you dont mind loosing a bit of weight,, you could scrape the top limb a bit,,
how are the arrows flying,,???
