Which CF decal?

I was thinking of ordering some CF decals from HLJ, made by by Studio 27. Which size should i get for which scale models. I suppose i will be doing 1:24 and 1:20. s, m or l?

I'm not familiar with the Studio 27 decals, but I recommend Scale Motorsport's CF decals. They may be more expensive, but its worth it. They come in 1/12, 1/20, 1/24, and 1/43. http://www.scalemotorsport.com

S27 make 1/24 1/20 and 1/12 (s m l )

Btw, S27 is the most expensive, and I don't really like the look of it.. just my opinion

Thanks for your input. I might get some and make my own mind up as it seems to be the only make HLJ has. I don't really want to be making credit card purchases alll over the net.

Smaller the better usually. If you are building 1/24 and 1/20th then the small and medium sizes are the ones you want. Large would be best saved for 1/12th scale. S27 have a different pattern that looks really good in the right circumstances.
