I bought a GSB108 1L for back bay/schoolie action last month,wrapped by Lou Caruso. I chose this blank for it's purported ability to handle lures less than 2 oz. Haven't fished it yet.
I also bought a GSB120 1L & 1M from a guy; he had these wrapped by Al Goldberg. Both rods have had 4" cut off from their tips. I had a chance to cast both but have not hooked up w/ any of them.
I bought the 120 1L for overall use for inlets & beach fishing, to throw 1 -4 oz. I will probably use this rod, as well as a GSB132 1L for most for my surf needs. It threw up to 3 oz very well with the tip modified. The 120 1M I got for jetties, eeling, & Montauk rocks. However, this rod's handle is about 3" longer than on my 120 1L for some serious lifting power. The former owner of this rod used it for eeling off jetties and whupped many large with it.
I also have a factory rod XS101MC rated 2-5 oz for conventional plugging & eeling. I won't cut the tip on this one since I think I can load it more easily as a 10' er.
Enough rambling. To answer your question, I think cutting down the 120 1L 4" off the tip will probably suit your needs well, especially if you need the length to steer fish from the rocks. Then again , the 120 1M will be more durable and powerful in these rocky holes you fish and still handle the stuff you like to throw fairly well. I think I need another 120 1M, but this time wrapped convench.
Good luck!
