Since you are not a beginning tyer, I would not recommend a kit. I started tying with a kit and do recommend it for beginners who don't know what they want to tie. I didn't; I just wanted to start tying and it worked out for me. Yes, a lot of the materials, and even the tools aren't top notch, but I'm still using some of them 30 years later. The point is, it got me started. But back to your question, since you already know what you're doing, don't buy a kit. As stated above, go a-la-cart and get what you want.
I'm sorry you lost everything. Good luck.
