While Mavina's is not top end, it's certainly not bad. The main drawback is it speed. With a base of 10 and no built in ias, you've got to get tons of ias anywhere else. Depending what skills you use though, it may not be a problem (it's certainly not a serious problem for strafe, but it may be for cold/freezing arrow).
So you can go for either ultra speed and low dmg, or a lower speed and high dmg. Before Windforce, you do have Eaglehorn, that while being realtively slow, it does has great dmg (and huge bonus to ar).
You should really say what build are you playing to get the best bow for you
