Looking for camshaft advise... 2110, Bus, Engle 110 or V26?

Thanks for any input. I am currently building a 2110 for my Bus. I am looking to build a mileage road trip engine. I am building a big engine that I plan to run near stoich, so I am not really trying to get every bit of power out of this engine size, I am looking for high fuel mileage. Best I have earned so far is 30mpg with a 1776 but the power was lacking a bit. It was a great engine, but I had to have my final lesson with that one on why not to use a remanufactured 30 year old Arizona baked engine case. For my new build I am running an Nos fat back German case. It is shuffle pinned, full flowed, and clearanced from Rimco. I have already gone in and done the hoover mod for the cam/lifter center oiling and plan to leave the lifters with a single groove since this case wont afford me the 'meat' to do the #3 cam bearing drilling. A friend and I both did our measurements and know there is no material where the bit needs to go. I ended that night with four hours of case porting, trying to reduce windage. Anyhow, this one will be pushing a lowered 65 Westfalia with 4.12 r&p & Bug gearing and 195/60/15's. I plan on raising the Bus back up eventually so I will consider my last transmission for that which was 3.88, Bus 4th, .082 rd's. That trans requires the torque! A healthy 2L was needed, prior to my 1776 & lowering(that too was a weak case). The main reason why I went away from that transmission was without the torque monster I could not get over 23mpg with several different builds, 1776 with single ports, dual single throat, etc. (& I mean etc. I had the touch of 28mpg with a couple of engines a decade ago and have chased that since. A roof rack is worth 5mpg I had found out.) Sorry for the long intro, but I know it is needed info for pure help with this cam decision. The engine is, 82 cb crank, stock weight flywheel, stock length rods, 90.5 aa's, cb lifters, Ported stock valve heads, heater boxes, Abarth style stock German Bug exhaust that I have added the two extra tips, serving breakfast is a beautiful set of dellorto 40 drla's with match ported manifolds. Thanks in advance for all advise. I can buy whatever cam at this point but I am leaning towards a Engle V26, which is Berg's 309, for use w ratio rockers. I had previously used this cam with 1.1 rockers on my old 76*90.5 and cb044's. The engine rocked. It idled amazingly smooth. Power rolled on so well, torquey right off the bat, and spun up with power on top, top for me on my engines is 5k. I would build that engine combo again for a Ghia or Bug in a heartbeat. It drove like a fuel injected 911. Power everywhere, a perfect driver engine. It did great when I put it in the Bus but wow what a difference. Funny how putting another 1500lbs on top slows down a lion's roar! I must have read somewhere that it could be run with stock rockers but there is nothing on the net like that I could find. I was considering this cam with 1.25's so I could have the oil flow through the adjusters like Hoover explains. Does anyone know if it is a bad move to do the v26 with 1.25's? Should I just go with the 110 cam and close her up? I am keeping in mind that both transmissions put me at about a 4k rpm @ cruise, which is around 70-75 mph.
