Also gut/Alu at around 50lbs CP isn't stiff or uncomfortable, well, not when the Alu is fresh anyway. Firm side of crisp when hitting flatter, and different variations of buttery crisp depending on how much top you put on the ball. Gut/Alu is sublime but out of the reach of us mortal folk in terms of a standard, regular string combo.
I agree with Torres. 48 in a mid is OK, but as tension loss sets in things start getting too loose. Fed never experiences tension loss.
