In my youth I always played with ashaway crossfire 2 because I always broke strings quickly. When Polyester strings came out I made the switch starting with luxilon ace moving onto Alu Power. Both Luxilon strings gave me golf/tennis elbow something that I never had with crossfire. Tried the ALU power hybrids with VS Gut, Poly in the mains & gut crosses at low tensions was still painful to my elbow but putting the gut in the mains and poly in the crosses increased the comfort by 100 % and played fantastic with far more spin than the reverse setup. Only problem was that I would only get 2 matches before they broke. So I went back to kevlar but still wanted poly in the crosses because I liked the fact that Poly as a cross string will keep your mains from moving all over the shop. I think I may have been the 1st person to post a thread about this hybrid on talk tennis and it seems that it is becoming more popular although there are many who are not willing to try because they presume that this setup is the harshest of the harsh. I really don´t think that there any better control strings out there than ashaway kevlar and with sppp in the crosses the kevlar stays firm and doesn´t move at all. This particular hybrid lasts for a very long time and it really doesn´t matter about tension loss because you won´t be spraying balls long. In Fact this is one string that peformance just gets better and better through out it´s lifespan which for me could be anything upto 6 months. Multis like tecnifibe x1 are great but would only last me about a set, Soft poly setups like topspin cyberflash where good but didn´t offer the level of control of the kevlar string and they would lose tension after about a months play. For those people who are willing to try the kevler/sppp I recommend to string at low tensions, you will still have superior control.
