You don't need a cloud to loop downwind smoothly. It's all technique. Start riding dw first then loop. Find the sweet spot of looping with minimal pull then but kite not falling out the sky.
Sorry Plummet , despite being a fan of yours for me the Cloud kites and my 4m UNO (obtained based on your comments) at my skill level make everything easier.
As in previous posts I also have a mutant and love it for its versatility but it's foiling as first choice.
