It's not too much of a change in swing style if you string it with the right strings. I would suggest looking into Pro Supex Big Ace, I used to string it in a full bed at 62lbs and this controlled the power a lot. If you don't want to string that high I would suggest a hybrid of any low powered poly in the mains and a thicker synthetic gut in the crosses.
Also, I added a lot of lead tape under the handle and replaced the grip with a leather grip to make it very head light which also helped lower the power for me.
