Marking Randomiser vs Marking Applicator

Never having used these products, I would be grateful if someone can answer the following queries

1.  Apart from the price in credits, please explain the difference between the Marking randomiser & Marking applicator.

2.  I have several Tobiano which I would like to change. Is there a possibility of getting the same coat pattern with the randomiser when others like tovero etc are available in the breed

3.  Is there a chance of getting no pattern with the randomiser

4.  Would using these tweaks affect acceptance to clubs if they were used on horses other than foundies? Could their use be seen anywhere?

Thank you in advance

1) Randomiser draws markings again from all possible within the breed, you can't choose which pattern it will be.  Applicator gives the markings you choose.

2) Yes

3) idk

4) That depends on a club, but I have never met problem with it. Usage of randomisers or applicators can be seen when somebody compares parents's genes with the horse.

3. i don’t believe so

Thank you both for you help
