I have just gotten a few of the Funtrix spin tops. I have not had the time to play a lot with them, but this morning I got the time to look at most of the DVD so I thought I would write something.
For the spin top the string is quite long so I have not managed to do a clean boomerang yet. I have to find the correct string length. (I hurt my shoulder last weekend doing off-road unicycling so I cannot practice much now). I guess the more experienced players can give better opinions about the spin top.
For the DVD I was positively surprised. I thought it would be a short DVD with just some simple tricks, but there is a quite large collection of tricks there. One thing is that they are only playing with Trompo Grande tops and they do not mention when they are using fixed tips and bearing tips, but I think they only used a bearing tip once.
It shows that it is a cheap DVD in the menu system, there was two tricks that linked to the same trick and I think one or more tricks was listed in more than one difficulty section. I have only tried the English menu so it might be better in the Spanish menu.
The filming of the tricks was good, they are shown from one or two angles and in slow motion so it should not be a problem to find out what they are doing. For me it was really the selection of tricks that was the best. They have a separate section with regeneration tricks like barrel rolls, suns, roller coaster, sewing machine, drumbeat, ... They have several advanced tricks as well, at least for me
like around the head wire walker, behind the head wire walker, staircase to heaven, ... Some tricks could be easier to understand if the camera was looking down at the top, but I think I understand what is going on in most of the tricks. And I guess it could be easier to understand if there was some text or explanation, but that is hard for a cheap multilingual DVD. Maybe there is some explanation in the Spanish language selection, I will have to check that later.
Here is a picture of the spin top next to a Trompo Grande I got from Salvador.
