Hi Chirs, I am now using Volkl Cyclone 17 (full bed), but feel a bit stiff on my shoulder and elbow. Would like to hybrid it with some inexpensive and durable synthetic. Noted from http://tt.tennis-warehouse.com/showpost.php?p=7027045&postcount=13, you suggest Mantis Comfort Synthetic I have shortlisted 2 synthetic strings, Mantis Comfort Synthetic 16 and Gosen OG Micro 16. How do you compare these two in terms of feel (i like lots of pop), and durability? Also, should be synthetic main, poly cross, right? As I assume the cyclone with cut the string easily. Many Thanks!
