can i still set the bow up to start useing bowstring and arrow squares to get starting points ?
Of course you can. I start out with mytiller set even at each end of the riser for checking poundage, axle to axle length, brace height and cam rotation/timing/synchronization. Then I set up my rest and set a preliminary nock point. THEN I do the tiller adjustments and get the nock point close to final. Once I get that done, then I can get down to tuning arrow flight.
It might sound time consuming but it's not nearly as time consuming as fighting with a stubbornpaper tear that just won't clean up, and all the aggravation and frustration that goes with it.
