Upgrading from ED80 to 110 something?

Hi All,
After an 18 month break from Astronomy, I have gotten the bug again and want to get back into wide field narrow band astrophotography.

I currently have a Saxon ED80 on the back of my Meade 12" Lx200R.
I just purchased a second hand QSI 583wsg with a full set of Astrodon GenII filters.
Amazingly there were two clear nights after the camera arrived and I had a ball. Spent my first ever Full nighter from 9:30 pm to 4:30am playing with settings, filters etc, and was blown away by how much more detail could see with th Ha filter as opposed to the Red filter. It really REALLY cut through the light pollution.

The focuser on my ED 80 is not good at all single speed and hard to focus. I was gonna update the focuser but am also considering getting another scope to replace it. I think a 110 is the biggest refractor I can get and still use the Meade to carry it.

I started looking at the Orion Eon 110 F/6 Apo looks like a nice kit. Then I saw the Long Perng 110 ED.. being carbon fibre it should be lighter. Then I noticed they Long Perng have a 110 F/6 Quadruplet for 2K which is my maximum budget. I assume a quadruplet will give flatter field? But I don't know anything about LP and am worried I will spend my last pennies on something and may und up with poor optics.

I did consider a newt, but I use an Orion A/O in front of the camera and I don't think it will be able to reach focus.

Any thoughts of info from someone that has a Long Perng?
