The Winstorm II is an excellent riser. My wife has one and has shot it both barebow and with a sight. If you are looking for an alternative to the Mizer at 25" try the
Samick
Agulla. It cost about the same as the Mizer and usually less than the Winstorm II. I agree with the comment to start with low cost limbs. I have seen folks shoot KAP T-REX limbs in competitions. They are low cost and easily upgraded (from a cost perspective) as you build strength and form. My wife also has a pair.
Most important is to buy inexpensive light limbs--they are easier to learn on. You see a lot of 40+ limbs for sale on the various archery forums. My son was progressing very well in Archery until he upgraded from 32 to 40 lbs limbs (31" draw length). His form has never been the same. There is the sense in the beginning that high draw weight is necessary. Quite the contrary, maintaining form for 144 arrows with a high draw weight is very difficult.
