I'll echo what AMB said. There is no downside to them. Once you invest in a good riser, you can buy and swap limbs until you find exactly what you're looking for. I've got a LH DAS Dalaa that I need to sell. It's either 17 or 19" I've also got a couple of "warfable" LH compound risers. They have not been converted yet.

My shoulders won't let me shoot any longer. I was in some high cotton when I bought that thing. Best shooting bow I ever had. You could swap limbs and go from lightweight target shooting to hunting limbs in about a minute.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
