I have a few but try not to switch during season. Each bow takes another set of arrows to make, and the process is time consuming and costly.
Each bow shoots a bit different too. Case in point: I'd been shooting a favorite juniper bow over the summer and shooting it really well. But for the small game season I switched to a hickory flatbow made just for the purpose. It's POI with the arrows I have for it is high and left of the POI of my juniper bow and its arrows. Maybe further matching of arrows would close that gap, but I have what I have right now. Both arrow sets fly well out of their respective bows -just a little differently.
In the field I've found the discrepancy a tough one to adjust for, being grooved in for the juniper bow. At least it's something I have to REMIND myself to adjust for. Come to anchor, then consciously make the adjustment, then release. I thought I had it licked this morning, socking pine cones and snapping mullein stalks at will, then I went ahead and missed two grouse, just high and left!
The first bird was through cover but I found a little hole amidst the tangle to slip an arrow through. I had to adjust for the trajectory since the hole was closer to me than the bird. I made the adjustment, and ... forgot to make the aiming adjustment again! I watched the arrow slip through the hole unscathed, only to fly just over the bird's back end! Add an additional calculation, like tracking trajectory, and I'm back shooting in my groove -the groove honed to the wrong bow.
