There are positive and negative points with various base-materials. Small partial pieces can be a bit ` fiddly` to work with.
Usually they do an ok job with the knots at the front because that`s usually the most visible.... hair is injected or can be V-looped into skin systems...the ` look` can be different than with lace...you can style /train hair on a lace base a little more easily., especially if you order ` freestyle`.
I can`t imagine you`d have very long hair on your front hairline ? Just that with very long hair, a thin skin may not be able to carry the ` weight` of very long hair. Some people complain that their hairline isn`t ` right` with skin systems compared to lace ..it`s a matter of individual taste I guess.
When it comes to glues /tapes [and I reckon glue would be best for your needs] it`s a matter of trial and error... what works well for one, may not be so good for the next person ..it depends on many ` local` factors.....but having said that , ORWG seems to be recommended by many wearers . Kind regards.
