I picked up the HT-225 ratchet crimpers and have a somewhat similar experience. My pin is a Williams System 6 (Time Warp) and I repinned all the connectors on the power supply board. For the double upped wires it was totally awesomesauce. Felt very secure and solid. For the single smaller gauge wires I felt the crimp could have been better especially on the insulation. I found that if I tugged a decent amount I could rip the crimp apart. To be honest though I felt as though the smaller gauge single wires are 22 AWG and I only had the 18-20 AWG Trifurcon contacts and so maybe that was part of the issue (Ed at GPE sells both 18-20 and 22-26 AWG trifurcon crimps; I'm guessing PBL only sells the 18-20 and maybe that may be the cause of the poor crimps). I gave a few of these a slight tug in the connector and they didn't just fall out so that was good. The only way I could give the HT-225 a definite yay or nay is if I could test out the single smaller gauge wires with the 22-26 AWG trifurcon contacts. I have a feeling it won't make much of a difference seeing as the crimp die only goes so far no matter the size of the contact unless I try to use the 22-26 AWG contact in the 24-30 AWG die slot but again that may just mash it to bits. If that is the case I'd probably go with the 1026-CT/BCT-1.

Update 6/4/2015: I finally got around to testing the HT-225 with the smaller 22-26 AWG contacts from great plains and this ratchet crimper rocks big time now. I use the smaller gauge contacts on single wires and the larger ones on the 'doubled up' wires and this crimper does both great!
