UHF Oozing

I have a rapido 2f with the UHF nut. Previously was using the original rapido, HF with a v6. With PLA, the prints are perfect, but with 'oozier' filaments, like CFPC, or LWPLA, the stringing is a nightmare. I've done all the regular tuning, but my question is do UHF/Volcano hotends require more retraction than compared to non UHF nozzles? To get more filament out of the melt zone? Is there anything else I should be considering? Like retraction length vs retraction speed.

You can try more retraction and also cooler temps. But, yes, I find volcano nozzles tend to ooze more than standard length
