Question for string saver users. How many do you put in and where? I was planning on put some string savers into my prestige pro to help the MT 17 I'm using last a little longer. My current plan is to basilcally put in string savers in the sweet spot area where each main and cross meet - the area where I noticed the most wear. Maybe a grid of about 9X9 roughly from the center of the string bed. But I was wondering if people do it a little differently, such as sort of alternating every other cross or do you need to put the string savers on the whole string bed?
