I want to get a bit more power out of my 12.5" f/5 dobbie smile

My shortest f/l eyepiece is a 7mm T6 which, when used with my soon-to-be-ordered Paracorr, will deliver about 260x. I'm thinking about a 6mm Radian (about 304x w/Paracorr) and/or a 5mm T6 (365x w/Paracorr). Or maybe a Pentax 5mm XW?

With my hand-driven dobbie I'm partial to wide field ep's so that limits my choices a bit and with the extra glass of the Paracorr I want to avoid barlows...

TIA for your input grin

Do you have a Barlow? If so then the 7mm doubled would give 3.5mm and more than enough power. Otherwise, the 7mm will be a 6mm with the Paracorr so I would say the 5mm would be a better solution and with the Paracorr it will give 4.25mm. The Pentax XW will give plenty of eye relief, but the T-6's will give more FOV. They are all good.
