squalls are great discs very long for a mid. the proline turn easier the the sp but also fade harder at the end. the sp is a very straight disc. if you are looking for a combo. get a proline squall a sp squall and a proline shockwave. the shockwave feels like a squall in the hand but is over stable. The squall will push out damn near as far as a stalker. (if the squall was easier to get in lighter weights it would still be in my bag).
I like the GM as well but it seem to fly very similar to a stalker to me just slower and with less glide.
