It's worth trying, if you're not trying to ignite things but rather project on clouds then you may want to set your 3E/G7 to an infinity focus, the single element is cleaner for yard burning work as seen through my safety glasses, it makes a clean line where as the 3E makes a shadow, but you may like the 3E for cloud spotting, try it and see, I like the 7mm long barrel G7 as it seems to be a different lens grind than the 9mm long lens barrel G7, you will only catch a few threads but it holds fine, I also had Lifetime17 make me some threaded disc and he can make you a heatsink threaded for the 3XBE I had him make one for me as the 3XBE threads are M11.4 x 0.5 and it's not a standard tap.
You can also put the lens into a longer holder. Anyway if you don't have a 3X you can try one for 60 dollars with the adaptor, M9 x 0.5 to 3XBE not the spiker adaptor.
I have been looking at wider stronger expanders and bid on some, I want VIS coated and they have to be 8mm x the mag wide for my corrected beam with at least 8mm input clearance if you see one you don't want I am looking.
The precise alignment and quality threads of the good expanders is needed for long range use of the power, for spot projection not so much.
Anyway the numbers of 1.75 line length at 75 feet and 7 inches at 300 feet is what the 44/3E/3XBE produces so if you can measure yours you can decide if it's better or not, 44/G2/6Xcyl/3XBE makes a 1/2 inch by 3/16 spot at 75 feet with a tighter hot center.
p.s. All my 44's have expanders, the primary lens only is good for desktop to 7 feet, maybe a bit more if you're patient, I'm not.
Actually a 44 with 3E will make a 7/8 line at 15 feet that will smoke through things slowly...too slowly for me.
