I broke a string the other day and I want to try out some string savers for increased durability - I also heard that they give a bit more spin and make a tighter stringbed. I am looking for some Babolat elasto cross ones. Before I get this racquet strung again, I was wondering - approximately how many lbs tighter do they make the stringbed? I would like to keep it feeling about the same tension as now - should I string it 1, 2, 3lbs lower? Any info would be appreciated. Thanks!
