Good observation RS. It can cause other problems but if everything is already OK then piking should be OK.
Big, Before you cut the bow tips off just add new string grooves below the old ones and string it up, check that everything is OK, exercise it and check the weight. If you need more off do the same again. There is a limit to how much you can pike a bow. When you get the weight you want(if it is possible with this bow) then cut the excess off the tips and reshape them. Pat
