I've ordered some Ashaway Dynamite Soft 18 and have read that Ashaway recommends stinging it "10-20% lower than standard". But 10-20% lower relative to what? The racquet's recommended range of tensions? And how does this effect hybrids? For example, for my PB 10 Mid I've strung the VS Mains at 50 and Xcel Crosses at 52. If I use the Dynamite 18 in the crosses, do I need to string at 45 and the gut at an equivalent amount lower? Or can I still do the Dynamite crosses at 52 and Pacific Prime 16 at 50? (I'm going to try Dynamite crosses and Pacific Prime mains). I liked Dynamite 18's numbers in the TW string performance database at 51, so I'm hoping I need not change. Any advice would be appreciated!
