Or should will transferring via racking tube -> ball lock post on pressurized keg with 1.5P extract left be enough protection?

I've metaphorically thrown away all my carboys and racking equipment. I ferment in a keg now, with a blowoff hose attached to the gas fitting. When blowoff stops, I'll swap the hose for a spunding valve set at low pressure. I keep it set around 3-4 psi, just enough that I can pull samples from a picnic tap to check gravity. When it's time to transfer (1.5p above fg), I gravity siphon to a purged keg via jumper lines. Then the spunden valve is set to full pressure to finish carbonating

Racking cane inside of an orange carboy cap with a pin lock fitting on the other end. I can either push it with CO2, or just get it started and let it siphon. I'll usually put a sterile air filter on the end of vent tube too.

I really like Polyclar and it has a proven record for flavor stability. RHB compliant since it can be removed via filtration. I turned a few others onto it, and they have agreed that it has really helped with flavor stability. Plenty of literature on the subject, but I am partial to this MBAA doc: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=13&cad=rja&uact=8&ved=0ahUKEwjNv6azhrLMAhXLWz4KHXZjBRU4ChAWCCgwAg&url=http%3A%2F%2Fwww.mbaa.com%2Fdistricts%2Fmidsouth%2Fevents%2Fdocuments%2F2010_11_12mustafarehmanji.pdf&usg=AFQjCNHHVgSrLj_uYMlMtRKhfxPsB3nYMg&bvm=bv.120853415,d.cWw

If you can keep oxygen less than .1 like they state and dose sweet! You are going to have a tough battle ahead of you! I have used PVPP, but couldn't keep o2 pick up low enough.

Plus then you have to filter it out. Filtering is a bitch to do without introducing oxygen.

Anyone tried a before and after reading with O2 conscious Gelling?

Maybe - Pre-Boil, Cool, and SMS dose 4oz of water. Add the Gelatin, stir, then very gently pour into the keg. Use a shortened dip tube on the lagering/serving keg.

Trying to think if there is any way to avoid a 4-6wk lagering period without adding O2.

The small percentage of the lager yeast still chewing down maltotriose long into the lagering phase is the best protection against oxygen. Why would you remove them with gelatin?
