Just wondering if anyone has any opinion on the advantages of Rec recoil guides over traditional snake guides. I'm planning on building Sage 490 SLT and want to do it with the best components possible. Are they really worth the extra cash? Also, does anyone know what the "t" listed on the guide spacing chart on the sage website means. The guides are listed as 1/0t, 1/0t, 1/0t, 1/0t, 1t, 1t, 1, 2, 4. Any info would be greatly appreciated. Thanks in advance.
