I of course use Jim Gillette's scales and I really like Lugo's warm ups.

Hey J, you know Kevin has almost all of Gillett's scales in his program in addition to his own exercises, so I find that really great. Basically, I'm doing like 3 programs, and it's working out quite well.

I sometimes warmup up with James Lugo's program, it's nice.

Normally I do some lip rolls and then RYV program. Sometimes I do 4 pillars after RYV, or 4p first and RYV after.

I have also BtC but I haven't yet adopted it into my practise routines. It looks good though.

Oh, and I do UBW a few times a week. When I started last autumn, I did Thomas Appell's program but I have quitted it after I started RYV. It's the only program that has vibrato exercise included. Thomas' program is OK but I can't stand it anymore without editing the lecturing away from exercises :)

Then I have the Vocal Power DVD but I'm saving it for a rainy day :)

And finally there is the CVT book but it doesn't come with a designed program.

I use CVT.

I also use CVT and I really like it BUT, it´s not a singing program, it´s more like a singing encyclopedia, wit tons of information and vocal research, but it´s not organized or planned in secuencial order, (which I don´t like) it´s up to you how to use it. I´ve recently checked out the breaking the chains program, and as far as I´ve seen on Kevin´s youtube channel, it´s pretty cool, it has the main 3 RYV exercises, Brett Manning and James Lugo exercises, and it seems that Gim Gillette´s too.

I love RYV, so it cannot be substituted for anything.
I've been combining it with Lugo's program. I really enjoy doing both of these programs but they don't seem to flow together nicely. It doesn't feel like a good combination. I tried combining it with Jim's scales too, even though it flows better, Jim's exercises don't challenge me as much (especially when singing 'through' the passagio) as Lugo's.

I do Breaking the Chains followed by RYV. Iys been working nicely. BTC allows me to really hit RYV even harder.

I'm trying SS again. At first I tried for 6 months and made no progress despite having an inherently pleasant voice. I'm remembering why - it's so hard and there is minimal guidance. RYV has given me much more optimism.

I'm also seeking another supplement. I'm kind of stuck between Arceneaux's latest offering and Breaking the Chains. I have aspirations to sing like U2/Radiohead/Muse, so I'm not sure if either of them are relevant. If you guys have any advice, feel free to give it. :-)

I use mainly Singing Success and they've been working great and now I just bought Ken Tamplin DVDs and some lessons with the guy, it's going to be awesome! RYV was the first book I read about vocal technique and singing and it's something that I will go back to for some detailed information whenever I feel I need to.

Singing Success exercises and "light and right"-approach really helped me correct many of the basics that I needed to deal with (I'm not done yet though!) and I'm already taking singing to a whole new level, now it's time for some Ken Tamplin stuff!

i use Thoma appell can you sign high c without straining after RYV warmups and then i go back to transcending tone and pharyngeal excercises , also now studying SLS from sett riggs
