Judo, throws for tall newbs

I'm a kind of tall Judo newb at 6'1" and am looking for simple throws to focus on. I'm working at O-soto-gari, of course.

I'd like to do seoi nage, but it's difficult because everyone else is 5'10", tops, except for an older shodan who just teaches. Drop seoi works but not in uchikomis.

I've read tai-otoshi, uchi mata and harai goshi are good for taller guys. Are they too advanced for a one month newb like me?

Thanks
