If a shop has something in stock and they won't let me try it then I won't buy it and you should do the same. Their policy on testing usually gets better if your credit card is leaving the building undented.
The best option of course is to build a relationship with the dealer.
If a shop can't tape up a set of limbs and set up a riser in a way that no cosmetic damage is done then that is their own fault. For starters they'd find that the tennis racket protection tape like that made by Babolat works a lot better than parcel tape
I have a set of Samick Extremes that have had at least 3,000 arrows shot off them and they are still pristine.
