There are a lot of TD Bear fans out there, and i have been building aftermarket limbs for quite a few years now to fit your Bear risers. These are available in #2 & #3 lengths in both my SS RC design and the Hybrid long bow design. I've had some excellent reviews on these limbs and they are listed on my website.
This last year i came out with a riser i call the "Bare Foot" riser. These are a unique design that does not use the flip latch hardware, but you can mount stock TD Bare limbs on, as well as order custom limbs built.
The original design i came up with used no hardware at all, but i had some issues with hair line cracks appearing on the limb butt caps that i found unacceptable. These have been field tested and have been proven to be very nice set ups. But i felt the need to revise the limb mount system to something better.
This new limb mount system has standard limb bolts with rubber washers that hold the limbs in place, with the addition of being able to adjust the tiller. Once the limbs are set up and tillered, they simply slide into the pocket with no adjustment needed. So taking them down and reassembly is very quick and no tools or adjustment necessary. These work much like an ILF system, only you can use your own TD Bear limbs, or my custom TD "Bare" limbs.
Another addition is that these risers come in 4 different sizes. I build the standard "A" & "B" lengths which are 15.5" & 19.5", and have added an "A+" which is 17.5" and a "B+" length which is 21.5" in length. The "A+" is becoming real popular, and i'm taking orders now.
Here is a video i did on the assembly and set up of a new "B+" riser.... Enjoy.... Kirk
