RE: Which kind for me (new law)
I do not unstring my bows between hunts. If fact once I put the string on (this week) it's there for the season unless I remove the string to turn it end for end (extends serving life IMO) or to re serve it. I do remove the strings, as well as the rubber pads from the disapator bars, off my Excaliburs during winter, while the bows are not in use.
The biggest cause of string failure is serving wear not stretching. Waxing the string and lubricating the deck (I use Jig A Loo, a dry silicone lube) prevents wear. Keeping the bow out of hot places is more to protect the limbs, I think.
The sting on my compound seems to wear faster than on my Excals; most likely because there is only one compound but two recurves. I think that the biggest cause of serving/ string wear is not only lack of maintenance but the draw weight of the bow. Bows holding back 200 lbs of pressure are bound to wear faster.
Boo makes VERY GOOD Flemish strings. They are quieter, and a bit faster than the stock Excel (endless loop) strings that come with Excals. I would definitely get a spare string. Changing out a string on a recurve is much easier than a compound. In fact, it can be done without a press (using nothing more than a $20 Stringer) something that cannot be done with a compound.
I make my own strings and re serve them about three times, so they last several years, but I do rotate a the strings when re serving them.
Keep asking questions, we'll try help any way we can.
