I didn't realize these were still on 'sale' last week until I called Timberwolf tools to ask some questions on the MT55.
Long story short, I now have an MT55(corded) and the P1CC.

My wife just looked at me cross eyed when I told her what a 'deal' I was getting and that I promised to sell my TS55C and Carvex PSC.
I haven't used the P1CC yet but used the MT55 right away. I ordered the 'set' with two 1.6 meter rails, clamps and rail connector.
The clamps seem spendy, but I am really impressed with how they work. One squeeze to secure the rail instead of two hands to fiddle with ratchet clamps. The Mafell clamp also seems less prone to pulling your rail off the line. The ratchet clamps can creep if you're not vigilant.
It might sound funny, but I'm excited about the rails and the connector method. I had a lot of frustration with Festool rails - even after trying the TSO GRC and buying a FS3000(slightly warped straight out of the box).
I'm happy to maintain and take care of tools, just don't enjoy fiddly or frustrating things.
I'm also really stoked to use the P1CC. All of the details they have thought of make this a tool that might get a lot of usage. Instead of previous jigsaw use that was 'only if I have to'.
p.s. I didn't notice any pulsing or weird noise with the MT55. For what it's worth, it sounded smoother and less like grinding rocks than the TS55(C).
p.p.s As others have mentioned, Jeff is awesome. I called and pestered him for several minutes last week before ordering. He answered all my questions and provided good insight into the tools and use without any sales bs. He was also seemed genuinely enthused about the product and gaining me as a customer. And their service during and after the order was great.
