Ribbon method requires the FR edge to be solved while TN method does not.Basically learn TOLS and normal TTLL first. Then depending where the dfr corner is Use a different alg to force The other sets of TTLL or to Force PLL. You can basically take the good things from what you've made and add them to the ribbon method for more of an option select.
If TN method also forces to a TTLL set, TNLS will have a lot of algs. Currently TNLS only uses OLL, OLS-FE, VLS, they are very familiar.
