I tried the RPM blast 16 recently @ 55lbs and really liked it. Had it as a full bed in my C10. Thought it was reasonably soft (i used to use X1 which was obviously softer) but had fantastic spin and good power. Are there other strings out there that I should consider? My priorities are 1) Soft 2) Similar bite for spin 3) Durability - would like the strings to last 10-15 hours at least. Heard Cyclone, Blackcode are good options also.
